WebJan 12, 2024 · Optuna allows to call the same distribution with the same name more then once in a trial. When the parameter values are inconsistent optuna only uses the values of the first call and ignores all following. Using these values: {'low': 0.1, 'high': 1.0}.> So this doesn't seem to be a valid solution.
